United States Air Force

* The Air Corps became a subordinate element of the Army Air Forces on 20 June 1941, and was abolished as an administrative organization on 9 March 1942. It continued to exist as a combat arm of the Army (similar to the infantry, armor, or artillery) until abolished by reorganization provisions of the National Security Act of 1947 (61 Stat. 495), July 26, 1947.

**The Army Air Forces were abolished by Transfer Order 1, Office of the Secretary of Defense, September 26, 1947, implementing the same provisions. Transfer Order 1 was the first of 200 Army-Air Force transfer agreements drawn up in June and July, 1947, and ordered the transfer of all military and civilian personnel of the Army Air Forces to the Department of the Air Force and the USAF. The final transfer order was signed June 22, 1949.

, the first all-metal monoplane bombers, and new fighters.

In 1935, as a result of recommendations from two civilian review boards, the next advancement toward independence for the Air Force occurred when all flying units, which heretofore had been distributed to various ground commands, were grouped together as an aerial task force under one air commander as the General Headquarters Air Force. The Air Corps, headed by the Chief of the Air Corps, continued as before but now held responsibility only for supply, airfields, and training, in effect splitting the Air Force into two parts. Both were commanded by major generals (Frank Andrews and Oscar Westover

During World War I, aviation technology developed rapidly; however, the Army's reluctance to use the new technology began to make airmen think that as long as the Army controlled aviation, development would be stunted and a potentially valuable force neglected. Air Corps senior officer Billy Mitchell began to campaign for Air Corps independence. But his campaign offended many and resulted in a court martial in 1925 that effectively ended his career.

, saw the lack of public, congressional, and military support that Mitchell received and decided that America was not ready for an independent air force. Under the leadership of its chief of staff Mason Patrick and, later, Arnold, the Air Corps waited until the time to fight for independence arose again.

 took the lead, calling for a vastly enlarged air force based on long-range strategic bombing. Organizationally it became largely independent in 1941, when the Army Air Corps became a part of the new U.S. Army Air Forces (AAF), and the GHQ Air Force was redesignated the subordinate Combat Command. In the major reorganization of the Army by War Department Circular 59, effective March 9, 1942, the newly created Army Air Forces gained equal voice with the Army and Navy on the Joint Chiefs of Staff

 and complete autonomy from the Army Ground Forces and the Services of Supply. The reorganization also eliminated both Combat Command and the Air Corps as organizations (the latter became a combat arm until 1947) in favor of a streamlined system of commands and numbered air forces for decentralized management of the burgeoning Army Air Forces.

The reorganization merged all aviation elements of the former air arm into the Army Air Forces. Although the Air Corps still legally existed as an Army branch, the position and Office of the Chief of the Air Corps was dissolved. However, people in and out of AAF who remembered the prewar designation often used the term "Air Corps" informally, as did the media.

. Spaatz began daylight bombing operations using the prewar doctrine of flying bombers in close formations, relying on their combined defensive firepower for protection from attacking enemy aircraft rather than supporting fighter escorts. The doctrine proved flawed when deep-penetration missions beyond the range of escort fighters were attempted, because German fighter planes overwhelmed U.S. formations, shooting down bombers in excess of "acceptable" loss rates, especially in combination with the vast number of flak

The Eighth Air Force had attempted to use both the P-47 and P-38 as escorts, but while the Thunderbolt was a capable dog-fighter it lacked the range, even with the addition of drop tanks to extend its range, and the Lightning proved mechanically unreliable in the frigid altitudes at which the missions were fought. Bomber protection was greatly improved after the introduction of North American P-51 Mustang

 fighters in Europe. With its built-in extended range and competitive or superior performance characteristics in comparison to all existing German piston-engined fighters, the Mustang was an immediately available solution to the crisis. In January 1944 the Eighth Air Force obtained priority in equipping its groups, so that ultimately 14 of its 15 groups fielded Mustangs. P-51 escorts began operations in February 1944 and increased their numbers rapidly, so that the Luftwaffe suffered increasing fighter losses in aerial engagements beginning with Big Week
